I’m very happy to see our paper published in Political Geography. We show that your country of residence influences your waiting time for an appointment at a German diplomatic mission. These differences are substantial and far from random.

Zitat von Dr. Niklas Harder:
Wartezeiten auf Termine an deutschen Auslandsvertretungen sind die erste Hürde auf dem Weg nach Deutschland. Unsere Untersuchung zeigt, dass das Herkunftsland entscheidet, wie hoch diese Hürde ist. 

Gute Migrationspolitik braucht Transparenz und gleiche Chancen für alle motivierten Einwanderer*innen, egal aus welchem Land. Hier bietet sich eine öffentlich zugängliche Plattform mit den aktuellen Wartezeiten an, etwa als Teil des Auslandsportals des Auswärtigen Amtes. Transparenz ist auch die Grundlage dafür, die Frage zu diskutieren, wie die unterschiedlichen Wartezeiten entstehen.

Langes Warten oder kein Termin – Globaler Süden wird im dt. #Visasystem deutlich benachteiligt. Das zeigt die Analyse von @deutschmann.bsky.social, @eui-eu.bsky.social, @niklas-harder.bsky.social & @alexandra-orlova.bsky.social @politicalgeography.bsky.social

Glad to see this out at @ajpseditor.bsky.social! I show that the immigration-crime issue, when salient, can shift leftist cosmopolitans to the Right. This is due to leftist voters being more conservative on crime than leftist parties.
